Aaronia AG - RF and MW Equipment

Aaronia Designs and Manufactures measuring equipment and develops technologies in frequency measurement, robotics as well as EMI/RFI screening/shielding.

Aaronia AG -  RF and MW Equipment

They Specialize in the design of precise high-frequency measurement devices and autonomic robotics-systems.

The SPECTRAN XFR V5 PRO is a portable Real-Time Spectrum Anaylzer, designed to capture even shortest signal transmissions. It´s scanning speed and recording time is without competition, the Analyzer scans 20GHz in less than 20mS making it the world´s fastest counter-surveillance receiver.

Real-Time Outdoor Spectrum Analyzer Spectran

Several helpful features allow a deep investigation of the Real-Time measurement or recorded data, e.g. a 3D Spectrogram view which displays a signal like newer seen before.

Facts of EMI and RFI from the Inside

Electromagnetic interference (or EMI, also called radio-frequency interference or RFI when in radio frequency) is disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.

170 – 1100 MHz with omni directional H-plane pattern

Who would know better about Radio Frequency Interference and ElectroMagnetic Interference more than the Hams or Amateur Radio Community.

If they have to communicate effectively using limited resources, they have to deal with EMI/RFI effectively, While they build their equipment or combat Noise from other Machines and Installations nearby.

EMI RFI Mains Filters

This problem needs more practical involvement and experimentation to learn, compared to learning something like Digital Electronics.

Equipment and Electricals like SMPS, AC/DC Drives, Motors, Solenoids and CFL Lamps are to be built/reinforced for low EMI/RFI emission/radiation.

Sensitive Medical Equipment like ECG or even a Aircraft can be seriously affected by Noise.
